That's what I strive for. ;-)

This would be very confusing (depending on the domain logic): If no 
category is selected in the Frontend, all Products without a category 
will be shown?!

I'd like to take the most restrictive edge-case: ... no Product will be 
shown. And add a check for an incoming NULL if necessary to show all 
Products if no there was no selection.

class Tx_MyExt_Domain_Model_Product extends ... {

	/**
	 * @var 
Tx_Extbase_Persistence_ObjectStorage<Tx_MyExt_Domain_Model_Category>
	 */
	protected $categories = NULL;

}

$query->matching($query->contains('categories', 'foo'))

The property definitely does not contain 'foo' as a category -> empty 
result set.

This is ambiguous. "Without a categories property set" (categories === 
NULL) or "Without a category" (count($categories) === 0).
